Hi I'm looking for someone who wants to trade there EFR6758 for my EFR6258. My turbo has about 3,000 miles and is in excellent condition, ceramic (VHT spray paint) turbine housing. I will pay for shipping both ways. I am only interested in EFR t25 flanged turbos.
Thanks,
Mike

 

That would be a hard trade with low incentive. Both are great turbos. Why the switch for marginally more? Why not jump to the 7163?

 

Yea I'm hoping someone wants to trade a little more power for a little more response. In trying to meet my goal of 400whp and I have doubts I will get there with the 6258. I would go for the 7163 of i had a twin scroll manifold. Thanks for the bump!

 

They have a t25 flange EFR7163 at the sacrifice of using a 0.85 A/R.

You have a turbo in hand, have you had it pushed? You have doubts, but have you tried? Why not make sure you have a limitation before self imposing one?

 

If I would have been smart and built a 1.8L i would probably consider the t25 flanged 7163, unfortunately i am not a smart man lol. I'm currently at 18psi with water meth, i'm still working on getting my knock sensor up and running before a switch to e85 and run all of it. I think my current turbo will probably touch the mark, running the turbo full tilt all the time. If i could make the power with a little less strain on the turbo, less heat generated, and a few less psi I would be more comfortable.
